Axial length (AL), anterior chamber depth (ACD), keratometric power (K), and corneal astigmatism (CA) were measured using partial coherence interferometry.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The mean patient age was 72.5 \u00b1 8.5 years. The mean AL, ACD, and average K were 23.5 \u00b1 1.6 mm, 3.1 \u00b1 0.5 mm, and 43.9 \u00b1 1.5 D, respectively. The mean CA was 1.02 \u00b1 0.76 D. Notably, 39.8% of eyes had CA \u2265 1.0 D and 9.3% had CA \u2265 2.0 D.
